A method for forming a balloon for a dilatation catheter may utilize the steps of extruding a tubing preform of a polyester resin and then blowing the tubing into an oriented balloon, wherein the tubing preform is dried prior to blowing into the balloon form. Other process steps by which balloon cone and waist thicknesses may be reduced involve varying the axial tension and blowing pressure at several stages as a mold containing the balloon preform is dipped into a heating medium. Specifically, tubing of a thermoplastic material is placed in a mold and blown by pressurizing and tensioning the tubing and gradually dipping the mold into a heated heat transfer media so as to sequentially blow a first waist, a body and a second waist portion. The tubing is subjected to a relatively lower pressure while the body portion is blown than while the first and second waist portions are blown.
